DQL - leftJoin（）錯誤：預期文字，得到了 '加入'

Question

此代碼：

$builder->select('p') 
    ->from('ProProposalBundle:Proposal', 'p') 
    ->leftJoin('ProProposalBundle:Proposal:Vote', 'v') 
    ->leftJoin('ProUserBundle:User', 'u') 
    ->andWhere('v.proposal = p') 
    ->andWhere('v.user = u') 
    ->andWhere('v.decision = "in_favor" OR v.decision = "against"') 
    ->andWhere('u = :user') 
    ->setParameter('user', $options['user']) 
    ->andWhere('p.community = :community') 
    ->setParameter('community', $community) 
    ->andWhere('p.archived = :archived') 
    ->setParameter('archived', $options['archived']) 
    ->leftJoin('p.convocation', 'c') 
    ->andWhere("p.convocation IS NULL OR c.status = '" . Convocation::STATUS_PENDING . "'"); 

    return $builder->getQuery()->execute(); 

返回錯誤：

[Syntax Error] line 0, col 106: Error: Expected Literal, got 'JOIN' 

這是所形成的查詢：

SELECT p FROM ProProposalBundle:Proposal p LEFT JOIN ProProposalBundle:Proposal:Vote v LEFT JOIN ProUserBundle:User u LEFT JOIN p.convocation c WHERE v.proposal = p AND v.user = u AND (v.decision = "in_favor" OR v.decision = "against") AND u = :user AND p.community = :community AND (p.convocation IS NULL OR c.status = 'pending') ORDER BY p.created desc 

LEFT JOIN缺少ON或WITH的情況。問題是：我在做什麼錯誤的DQL查詢？我用leftJoin()方法錯了嗎？

學說ORM需要你告訴它關係被加入，而不是實體本身（你做得很好用p.convocation）：

$builder->select('p') 
    ->from('ProProposalBundle:Proposal', 'p') 
    ->leftJoin('ProProposalBundle:Proposal\Vote', 'v', 'WITH', 'v.proposal = p AND v.user = :user AND (v.decision = :in_favor OR v.decision = :against)') 
    ->setParameter('user', $options['user']) 
    ->setParameter('in_favor', 'in_favor') 
    ->setParameter('against', 'against') 
    ->andWhere('p.community = :community') 
    ->setParameter('community', $community) 
    ->andWhere('p.archived = :archived') 
    ->setParameter('archived', $options['archived']) 
    ->leftJoin('p.convocation', 'c') 
    ->andWhere("p.convocation IS NULL OR c.status = :pending") 
    ->setParameter('pending', Convocation::STATUS_PENDING); 

return $builder->getQuery()->execute(); 

編輯：我倒投票的關係，你的評論和刪除無用的WHERE子句（Doctrine自動解決了JOIN ON子句，我還在可選參數（WITH在DQL中）中傳遞了一些關於連接的WHERE子句

edit2：沒有建議和表決之間的關係，不確定它是否有效。

edit3：最佳做法是對所有WHERE子句中的值使用setParameter。
